Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72702, here are decompositions:
- 13 + 72689 = 72702
- 23 + 72679 = 72702
- 29 + 72673 = 72702
- 31 + 72671 = 72702
- 41 + 72661 = 72702
- 53 + 72649 = 72702
- 59 + 72643 = 72702
- 79 + 72623 = 72702
Showing the first eight; more decompositions exist.
